kegster Posted January 26, 2009 Share Posted January 26, 2009 Hi, I bought an amp and a pair of speakers but had no idea about ohms until now. Below is the details of both the amp and speakers and im wondering will my setup cause problems or should I return any of the items? Amp - Samson servo 170. - Servo-controlled stereo power amp in two rack spaces- 85 watts per channel into 4 ohms- Wide, linear 20 Hz to 50 kHz frequency response for superior audio performance- Relay-controlled power-on circuitry prevents speaker "thumps"- Front-panel Clip and Idle LEDs for both channels- Balanced 1/4" TRS inputs- Unbalanced RCA inputs- Circuitry protection against overheating and over-current- 1/4" and push-spring terminal outputs- Independent left/right input level controls with 41 detents- Bipolar amplifier design- Convection-cooled design for quiet performance Speakers - JBL Control 1 Pair- Frequency range: 50Hz - 20kHz (-10dB) - Power capacity: 100 watts (2 x 50W) RMS - Sensitivity: 89dB - Nominal impedance: 8 ohms - Components: - 100mm (video shielded) low frequency bass driver - 12mm (video shielded) titanium laminate tweeter - Enclosure material: structural foam - Finish: black - Dimensions (W x H x D): 155 x 228 x 139mm - Weight (each): 2.4kg - Wall mount brackets included Please help, im confused. Thank you!! Link to comment Share on other sites More sharing options...
Simon Lewis Posted January 27, 2009 Share Posted January 27, 2009 Your amplifier will deliver about 50W to each speaker. It won't be powerful enough to drive the loudspeaker to its maximum capacity, but if it's loud enough for your needs without the speaker sounding distorted, all should be well.

kegster Posted January 27, 2009 Author Share Posted January 27, 2009 Thanks for that. Whats the ideal amp I should be using for these particular speakers? Link to comment Share on other sites More sharing options...
smalljoshua Posted January 27, 2009 Share Posted January 27, 2009 Your setup will work just fine. If you want to have the amp matched to the speakers perfectly* you want an amp that will deliver 100w RMS into 8Ohms. *It is widely accepted that twice the speakers' rated power is a good match for an amp.

Bobbsy Posted January 27, 2009 Share Posted January 27, 2009 Well, there's a convention for sound reinforcement use that the amplifier should be capable of roughly twice the power rating of the speakers. In this case that would mean an amp of about 100W RMS per channel into 8 ohms. HOWEVER... You don't say what your application is but, since we're talking Control 1 speakers here, we're not exactly talking about stadium concerts! Control 1 speakers are more normally used as nearfield monitors in a control room or a similar application. I've used them a lot in portable edit suites etc. and tended to use amps similar or less powerful than the one you have--often as low as 25W per channel. For ordinary use your amp should be just fine...and more than loud enough. If, for some reason, you need higher SPLs, then frankly I wouldn't be using the Control 1 model anyway. (And I used to help out at a youth group that had exactly that amplifier...nothing special but it was a workhorse that the worst efforts of the teenagers never managed to kill!) Hope this helps.

Chappie Posted January 27, 2009 Share Posted January 27, 2009 Can I ask where the Control 1 specs came from, as I was under the impression it was a 4Ω box, not 8Ω? Link to comment Share on other sites More sharing options...

Most of the legacy and Pro Control 1s are indeed 4Ω, but some of the new budget versions (see CPC) are 8Ω Link to comment Share on other sites More sharing options...
kegster Posted January 27, 2009 Author Share Posted January 27, 2009 Thanks for the advice guys. Yeah they will be used as nearfield monitors and they certainly don't need to be cranked up so looks like this amp will do the trick. thanks. Link to comment Share on other sites More sharing options...

I didn't know they did a domestic version until now. I wish the Pro box was 8Ω as standard though, it would be far more practical! Link to comment Share on other sites More sharing options...
